form of signal whichcontains lamps for illuminatingtheflstopiqand turning signal g meanswith a1 simplearrangement of .theaster ing: column below the steering wheel for: en-.

abling ;the .driver to 3 close the circuit of the! a turningsignal meansfwithout removing his handsfromtliewheel.

Another. object of the invention is tomake thepartsadjustable soxthat they canbeused I with differentsizeslofysteering wheels.

Each enlargement is provided'with oppositelyarranged ears 5 and the ears onthe two en.-

largements are fastened together by the bolts toward and away from the wheel. A tubular Figure 2 s a bottom planview of the switch e e I i pressed. j Figure 7 is a view of the signal device with extension 7 is telescopically arranged in the outer end: of each arm and said extension is heldin edpisted positlon by a screw 8 passing throughithe armvl'and engaging the exten- -sion.;: A push'button 9 i'sslidably arranged in theouter endoi' each extension and is normally held projected by a spring 10 arranged in the extension between the button and=a perforated partition 11 in said extension. A headed rod 12 is carriedby thebuttonand passes through the perforation in the parti- 'tionwith its head arranged to engage the pair of spring contacts 13 when the button is pushed inwardly so as to bridge the contacts a and thus close an electric circuit through the conductors 142 whichipass through the arm. and through a passage 15 formed in each enlargement 2 and then the conductors are passed through apipe 16 which has its upper end clamped between the enlargements 2.

This pipe extends parallel with the steering column. 1 a a One of the conductors isconnecte'd with the battery B of the caror other source of is connected with the second switch 13 is connected with a lamp 18, these lampsbeing 1 placed in the end compartments 19 of a casing 20which is adapted to be fastened to the rear part of a motor vehicle.

When the vehicle is to be turned tothe left, the operator will touch the button 9 on the left hand side of the member A so as to 'closethe circuit to the lamp 18 to illumi nate the left hand turning signal and when thevehiclejis to be turnedto the right,.thefl other button 9 is pushed inwardly to close the circuit of the lamp forindicating that the vehicle is'to make aright turn... As shown in Figure 5, the lampsareall grounded. to a part of the vehicle. i
